This invention pertains to motors suchas pressure-chamber 8, the valve 7 operating are employed in the propulsion ofa'utom'o- 5 within said pressure chambeng; Connected to biles and for anypurposes for which an inthe pressure chamber 8 is a tank-13in which 1 ternal'combustion motor is usually employed. .a gaseous pr'o'pelling mediumiforthe" engine 6 More particularly the invention comprises 1 mayconveniently behere introduced und risa a cylinder head which may be substituted pressure, the supply of'p'rop'ellant'beingjada for such structures now employed, and whlch justed by means of valve 141' inter-posed beis adapted, because of its construction, to utitween thetank13 and the housing 8 defining liz e acompressed'gaseous fluid as the propelthe pressure chamber; This valve l is in I 10 lingmedium of the motor or engine. serted infla pipe '18 connectingthe tank 13 Referring to the drawings a with the chamber 8.

It is desired to emphasize the fact that the specific adaptationof the invention as herein described in. the specification and drawings is illustrative only and it is considered obviousthat many modifications thereof canf with said exhaust port and said cylinder con- 7 necting passage, a lug projecting from said lower surface adjacent said depression and a pitman connected to said lug for moving said'valve alternately, to connect said cylinder connecting passage to said pressure chamher and to said exhaust port.
